Question

A car starts from rest and attains a velocity of 18 km/hr in 2sec.Find it accelaration.

Answer 1

Answer:

u = 0

v =18 km/hr = 18*1000/3600=5m/s

t = 2 sec

a = v-u /t

0-5/2=2.5m/s2

Explanation:

Answer 2

Answer:

Explanation:

Given-

v=18km/hr=5m/s

u=0

t=2s

a=?

a=(v-u)÷t

a=(5-0)÷2

a=5/2

a=2.5m/s^2

Hope this answer is helpful for u
